Will you exhaust all non-violent means to diffuse the situation before resorting to the use of a gun? Or will you shoot first and justify later?
I was taught to respect the proportionality of escalation. If a man raises his fists to you you raise your fists back. You don’t pull out a knife.
Most gun laws, at least here in civilized America, require that the person brandishing the weapon to demonstrate that (s)he had a
rational fear for his/her life. The rationality thereof, of course, is determined in a court of law by 12 jurors of the shooter’s peers.
Any law enforcement officer of any sort worth her salt will tell you that an American cannot legally, justifiably, shoot a person unless they had a
reasonable fear for their life. This is so important that we’re taught that so called “warning shots” are illegal precisely because shooting them as warnings necessarily implies that you didn’t in fact fear for your life (otherwise they wouldn’t be warnings and you’d be shooting toward center mass). It’s well understood among Americans who bear arms and are
decently trained therein, that one should never draw his weapon unless one intends to shoot. Period. If you pull it out, you pull the trigger.
Would you retreat if you had the opportunity to do so?
If it’s my property? No go. I keep shooting until he runs away. I cease shooting once he ceases to be a threat. “Threat” means a threat to either my person or my property. If I’m in public, then yes, as soon as he ceases to be a threat to my physical safety I will cease with my defensive behavior.
